Improved silicon steel plate belt surface cleaning device and cleaning method

Abstract

The invention discloses an improved silicon steel plate belt surface cleaning device and cleaning method, and aims at providing a cleaning device and cleaning method which can effectively prevent the situation that alkaline leaching liquid flotage is brought in an alkaline washing tank to block nozzles and can avoid the situations that the silicon steel plate belt surface cleaning quality is poor due to the fact that high-speed running belt steel brings alkaline liquid in an electrolysis cleaning tank into a water washing tank, and much inconvenience is brought to equipment maintenance and field safety environment due to water overflowing of the outlet side of a water rinsing tank. The cleaning device comprises an alkaline leaching tank, an alkaline washing tank, an electrolysis cleaning tank, a water washing tank, a water leaching tank, a water rinsing tank, a circulating system and a magnetic filter system. The alkaline leaching tank, the alkaline washing tank, the electrolysis cleaning tank, the water washing tank, the water leaching tank and the water rinsing tank are connected in sequence and matched with the circulating system and the magnetic filter system. The cleaning device is characterized in that a pair of nozzles is arranged in a belt steel upgoing area on the outlet side of an inner cavity of the alkaline leaching tank.

Description

technical field [0001] The invention relates to the technical field of silicon steel production, in particular to an improved silicon steel strip surface cleaning device and cleaning process. Background technique [0002] Before the silicon steel strip enters the continuous annealing furnace, the emulsion, rolling oil, anti-rust oil, iron powder, dust and other pollutants attached to the surface of the steel strip must be removed, otherwise it will seriously affect the quality of the finished silicon steel and the carbon content in the furnace. The service life of the set of rollers. [0003] At present, typical silicon steel strip surface cleaning devices such as figure 1 As shown, but in the cleaning process, due to the phenomenon that the high-speed running steel strip brings the lye in the electrolytic cleaning tank into the subsequent water scrubbing tank in the form of a liquid film, a small amount of lye exists in the water scrubbing tank, causing the steel strip Po...

[0003] At present, typical silicon steel strip surface cleaning devices such as figure 1 As shown, but in the cleaning process, due to the phenomenon that the high-speed running steel strip brings the lye in the electrolytic cleaning tank into the subsequent water scrubbing tank in the form of a liquid film, a small amount of lye exists in the water scrubbing tank, causing the steel strip poor surface cleaning

In addition, the steel belt running at high speed will also bring floating objects on the liquid surface in the alkali immersion tank into the alkali scrubbing tank, resulting in blockage of the alkali scrubbing nozzle and water overflow at the outlet side of the water rinsing tank, which will bring great harm to equipment maintenance and on-site safety. many inconveniences
